US 2026/0263167 A1 · METHODS AND SYSTEMS FOR TUNNEL PLANNING AND NAVIGATION

Abstract

Some examples are directed to a method for displaying, by a surgical controller on a display device, surgical guidance information based on at least one calculated value indicative of a compatibility, for together supporting a replacement ligament, of a first tunnel in a first bone of a joint and a candidate second tunnel in a second bone of the joint. Some examples are directed to a surgical controller configured to display the surgical guidance information. Some examples are directed to a method for displaying, by a surgical controller on a display device, surgical guidance information based on at least one calculated value indicative of a risk of convergence of a first tunnel in a first bone and a candidate second tunnel in the first bone. Some examples are directed to a surgical controller configured to display the surgical guidance information.

Claims20

Dependent claims

A method comprising:

storing, by a surgical controller, data defining a first tunnel in a first bone of a joint, the first tunnel having a first longitudinal axis;
tracking, by the surgical controller, a drill axis of an instrument with respect to a second bone of the joint;
defining, by the surgical controller, a candidate second tunnel in the second bone having a second longitudinal axis corresponding to the drill axis of the instrument;
calculating, by the surgical controller based at least on the candidate second tunnel and the data defining the first tunnel, at least one value indicative of a compatibility of the candidate second tunnel with the first tunnel for together supporting a replacement ligament;
and
displaying, by the surgical controller on a first display device, surgical guidance information based on the at least one value indicative of the compatibility.

3 more elements

A surgical controller comprising:

at least one processor configured to couple to at least a first display device;
a memory coupled to the at least one processor, the memory storing instructions that, when executed by the at least one processor, cause the at least one processor to:
store data defining a first tunnel in a first bone of a joint, the first tunnel having a first longitudinal axis;
track a drill axis of an instrument with respect to a second bone of the joint;
define a candidate second tunnel in the second bone having a second longitudinal axis corresponding to the drill axis of the instrument;
calculate, based at least on the candidate second tunnel and the data defining the first tunnel, at least one value indicative of a compatibility of the candidate second tunnel with the first tunnel for together supporting a replacement ligament;
and
display, on the first display device, surgical guidance information based on the at least one value indicative of the compatibility.
